Player career mode allows you to control player interactions and see headlines updated in real time. As a professional, you can choose your position and develop season goals by practicing. Your stats over 4 games will impact your ability values. If unsatisfied, you can adjust values or convert them to experience. New players can be signed if current players are fatigued or underperforming. When ready, players can choose to retire. FIFA 13 features changes to the transfer system like adding cash to player trades, loaning players with future/installment purchase options, and negotiating complex contracts between clubs and players.
